Expand description
When writing a match expression against RuleType
, it is important to ensure
your code is forward-compatible. That is, if a match arm handles a case for a
feature that is supported by the service but has not been represented as an enum
variant in a current version of SDK, your code should continue to work when you
upgrade SDK to a future version in which the enum does include a variant for that
feature.
Here is an example of how you can make a match expression forward-compatible:
# let ruletype = unimplemented!();
match ruletype {
RuleType::AllowedRenditions => { /* ... */ },
RuleType::ForceIncludeRenditions => { /* ... */ },
RuleType::MinBottomRenditionSize => { /* ... */ },
RuleType::MinTopRenditionSize => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when ruletype
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant RuleType::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
RuleType::Unknown(UnknownVariantValue("NewFeature".to_owned()))
and calling as_str
on it yields "NewFeature"
.
This match expression is forward-compatible when executed with a newer
version of SDK where the variant RuleType::NewFeature
is defined.
Specifically, when ruletype
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on RuleType::NewFeature
also yielding "NewFeature"
.
Explicitly matching on the Unknown
variant should
be avoided for two reasons:
- The inner data
UnknownVariantValue
is opaque, and no further information can be extracted. - It might inadvertently shadow other intended match arms. Use Min top rendition size to specify a minimum size for the highest resolution in your ABR stack. * The highest resolution in your ABR stack will be equal to or greater than the value that you enter. For example: If you specify 1280x720 the highest resolution in your ABR stack will be equal to or greater than 1280x720. * If you specify a value for Max resolution, the value that you specify for Min top rendition size must be less than, or equal to, Max resolution. Use Min bottom rendition size to specify a minimum size for the lowest resolution in your ABR stack. * The lowest resolution in your ABR stack will be equal to or greater than the value that you enter. For example: If you specify 640x360 the lowest resolution in your ABR stack will be equal to or greater than to 640x360. * If you specify a Min top rendition size rule, the value that you specify for Min bottom rendition size must be less than, or equal to, Min top rendition size. Use Force include renditions to specify one or more resolutions to include your ABR stack. * (Recommended) To optimize automated ABR, specify as few resolutions as possible. * (Required) The number of resolutions that you specify must be equal to, or less than, the Max renditions setting. * If you specify a Min top rendition size rule, specify at least one resolution that is equal to, or greater than, Min top rendition size. * If you specify a Min bottom rendition size rule, only specify resolutions that are equal to, or greater than, Min bottom rendition size. * If you specify a Force include renditions rule, do not specify a separate rule for Allowed renditions. * Note: The ABR stack may include other resolutions that you do not specify here, depending on the Max renditions setting. Use Allowed renditions to specify a list of possible resolutions in your ABR stack. * (Required) The number of resolutions that you specify must be equal to, or greater than, the Max renditions setting. * MediaConvert will create an ABR stack exclusively from the list of resolutions that you specify. * Some resolutions in the Allowed renditions list may not be included, however you can force a resolution to be included by setting Required to ENABLED. * You must specify at least one resolution that is greater than or equal to any resolutions that you specify in Min top rendition size or Min bottom rendition size. * If you specify Allowed renditions, you must not specify a separate rule for Force include renditions.
